Dynamic modelling with “MLE-energy dynamic” for primary school
No full textDuring the recent years simulation and modelling are growing instances in science education. In primary school, however, the main use of software is the simulation, due to the lack of modelling software tools specially designed to fit/accomplish the needs of primary education. In particular primary school teachers need to use simulation in a framework that is both consistent and simple enough to be understandable by children [2]. One of the possible area to approach modelling is about the construction of the concept of energy, in particular for what concerns the relations among substance, potential, power [3]. Following the previous initial research results with this approach [2], and with the static version of the software MLE Energy [1], we suggest the design and the experimentation of a dynamic modelling software— MLE dynamic-capable to represent dynamically the relations occurring when two substance-like quantities exchange energy, modifying their potential. By means of this software the user can graphically choose the dependent and independent variables and leave the other parameters fixed. The software has been initially evaluated, during a course of science education with a group of primary school teachers-tobe, to test the ability of the software to improve teachers’ way of thinking in terms of substance-like quantities and their effects (graphical representation of the extensive, intensive variables and their mutual relations); moreover, the software has been tested with a group of primary school teachers, asking their opinion about the software didactical relevance in the class work

No full textALTERNATIVE LEARNING TECNOLOGIES FOR STUDENTS WITH SPECIAL EDUCATIONAL
No full textn recent years the introduction of modern technologies has allowed students with disabilities to achieve a greater degree of autonomy and independence and favored a change in teaching that has become an increasingly "inclusive education", focusing on special educational needs and above all on their “hidden potential”. The increasing number of students with special education needs at the university level requires strategies to guarantee to every student the same rights. Today the learning processes make a large use of digital environment and the students with disabilities can successfully make use of specific technologies. We present a system developed at the University of Modena and Reggio Emilia based on digital white boards, tablets, and a repository for the audio-video recording of the lecture and of the learning resources specially addressed to students with special educational needs
Visual and gestural metaphors for introducing energy to student teachers of primary school and kindergarten levels
Full text linkThe linguistic expressions scientists and educators use for energy are in most cases expressions of the principal metaphor of substance, although energy is an imponderable concept. The substance metaphor is embodied and familiar to students, so we can rely on it as useful for helping them develop a productive framework for understanding energy. In this paper we will introduce a laboratory course for student teachers of primary school and kindergarten levels using visual and gestural metaphors for introducing energy
